What we know: How the New Zealand terror attack unfolded

(CNN)— At least 49 people were killed and more than 20 seriously injured in a terror attack on two mosques in Christchurch, New Zealand, on Friday. The unprecedented mass shootings were carefully planned, and have shocked the usually peaceful nation New Zealand Prime Minister Jacinda Ardern described the attack as one of her country’s “darkest days.” She said that the suspects held “extremist views” that have no place in New Zealand or anywhere else in the world.

Where the Christchurch shootings happened

A gunman targeted two mosques in central Christchurch at lunchtime Friday local time. Friday is the busiest day for many mosques around the world.

The first and most deadly shooting took place just after 1:30 pm at al Noor mosque.A graphic video which streamed live on social media for about 17 minutes purports to show a portion of the attack: In it, a man is seen driving through the streets of Christchurch before arriving at the mosque and eventually opening fire.

The horrific attack on al Noor Mosque, including the time where shooter returns to the car to re-arm, lasts approximately six minutes. As the shooter drove away from al Noor mosque, he opened fire on several people who were walking along the street, the video appears to show. Social media sites such as Facebook, YouTube and Twitter struggled to halt the spread of the footage, raising new questions about the companies’ ability to manage harmful content on their platforms.

Shortly after the livestream ended, a second attack took place at Linwood mosque. At least seven people were killed there and another died later at the hospital.A number of weapons were recovered at both locations. Ardern said improvised explosive devices were also found at the scene.

Our gun laws will change,” she said at a news conference in Wellington.Until Friday, the biggest massacre in New Zealand’s history happened nearly 30 years ago, when a man killed 13 people in a shooting rampage.
